InkAnalyzerBase.FindInkLeafNodes 方法
返回作为包含笔画数据的 ContextNodeBase 对象的所有墨迹叶节点。
命名空间: System.Windows.Ink.AnalysisCore
程序集: IACore(在 IACore.dll 中)
语法
声明
Public Function FindInkLeafNodes As ContextNodeBaseCollection
用法
Dim instance As InkAnalyzerBase
Dim returnValue As ContextNodeBaseCollection
returnValue = instance.FindInkLeafNodes()
public ContextNodeBaseCollection FindInkLeafNodes()
public:
ContextNodeBaseCollection^ FindInkLeafNodes()
public ContextNodeBaseCollection FindInkLeafNodes()
public function FindInkLeafNodes() : ContextNodeBaseCollection
返回值
类型:System.Windows.Ink.AnalysisCore.ContextNodeBaseCollection
作为包含笔画数据的 ContextNodeBase 对象的所有墨迹叶节点。
备注
墨迹叶节点的示例包括 Type 属性值为 InkWord、InkDrawing 和 InkBullet 的节点。
叶节点不包含子节点。
示例
下面的示例遍历 InkAnalyzerBase (theInkAnalyzerBase) 的所有墨迹叶节点,查找具有最低下限的叶节点。
' Find the ink leaf context node that has the lowest bottom bound.
Dim lowest As Integer = Integer.MaxValue
Dim lowestNode As System.Windows.Ink.AnalysisCore.ContextNodeBase = Nothing
Dim leafNode As System.Windows.Ink.AnalysisCore.ContextNodeBase
For Each leafNode In theInkAnalyzerBase.FindInkLeafNodes()
' Find lowest node. Note, AnalysisRegionBase.GetBounds() returns an
' array containing the left, top, right, and bottom bounds in order.
If leafNode.Location.GetBounds()(3) > lowest Then
lowestNode = leafNode
lowest = leafNode.Location.GetBounds()(3)
End If
Next leafNode
// Find the ink leaf context node that has the lowest bottom bound.
int lowest = int.MaxValue;
System.Windows.Ink.AnalysisCore.ContextNodeBase lowestNode = null;
foreach (System.Windows.Ink.AnalysisCore.ContextNodeBase leafNode
in theInkAnalyzerBase.FindInkLeafNodes())
{
// Find lowest node. Note, AnalysisRegionBase.GetBounds() returns an
// array containing the left, top, right, and bottom bounds in order.
if (leafNode.Location.GetBounds()[3] > lowest)
{
lowestNode = leafNode;
lowest = leafNode.Location.GetBounds()[3];
}
}
